See the conversation.  --Is the IEC type 2 inlet the same as the SAE J1772 type 2 inlet? --The European versions were equipped with a SAE J1772-2009 inlet as well until the automotive industry settled on the IEC Type 2 “Mennekes” connector as the standard inlet — since all IEC connectors use the same SAE J1772 signaling protocol the car manufacturers are selling cars with either a SAE J1772-2009 inlet or an IEC Type 2 inlet depending on the market. --Do they have any other different inlets? --There are also (passive) adapters available that can convert J1772-2009 to IEC Type 2 and vice versa. --What other differences are there? --The only difference is that most European versions have an on-board charger that can take advantage of three-phase electric power with higher voltage and current limits even for the same basic electric vehicle model (such as Chevrolet Volt / Opel Ampera). --Is the charging speed different? --SAE is developing a Combined Charging System with a "Combo Coupler" variant of the J1772-2009 connector with additional pins to accommodate fast DC charging at 200–450 volts DC and up to 90 kW. --What other standards are there? --
This will also use Power-line communication technology to communicate between the vehicle, off-board charger, and smart grid.
